An element has electronic configuration ...

An element has electronic configuration `1s^(2)2s^(2)2p^(6)3s^(2)3p^(4)`. Predict its group, period and block

A

Period = `3^(rd)`, block = p, group = 16

B

Period = `5^(th)`, block = s, group = 1

C

Period = `3^(rd)`, block = p, group = 10

D

Period = `4^(th)`, block = d, group = 12

Text Solution

Verified by Experts

The correct Answer is:
A
By observing principal quantum number (n), Orbital (s, p, d, f) and equating no. of `e^(-)` 's we are able to find the period, block and group of element in periodic table.
